De-sta-co 5905 Hold-down Toggle Clamp 750.86 Lb

Product Description

The DE-STA-CO 5905 is a manual hold-down toggle clamp with a vertical handle orientation and a flanged base, designed for workholding applications in fabrication, assembly, and machining operations. Built from forged alloy steel with an oxide finish, it delivers a holding capacity of 750.86 pounds (3,340 N) through a solid closed-end bar. The handle travels 70 degrees to lock, and the bar opens to 135 degrees for part loading and removal. With an overall length of 4.02 inches and an overall height of 6.51 inches, this clamp fits tight workstations where a compact, high-force hold-down is required. Machinists, fixture builders, and production assembly technicians are the primary installers.

The 5905 is suited for jig and fixture work on machine tool tables, welding positioners, and production assembly benches. Its flanged base with four mounting holes allows rigid surface mounting to steel plates, fixtures, and work tables. The 1.5-inch base width and 38.10 mm base length keep the footprint small while maintaining a strong mount. The height under the bar measures 1.27 inches, which defines the usable clamping clearance for workpieces placed beneath it.

Key Features

• 750.86 lb (3,340 N) holding capacity for high-force workholding
• Forged alloy steel construction with oxide finish for durability and corrosion resistance
• 135-degree bar opening for fast, unobstructed part loading and removal
• 70-degree handle movement provides positive over-center lock engagement
• Four-hole flanged base for rigid, vibration-resistant surface mounting
• Solid closed-end bar with 0.51-inch bar width for consistent clamping contact

Compatibility

Designed as an OEM-style hold-down toggle clamp for use in standard jig, fixture, and workholding applications requiring a vertical-handle, flanged-base configuration.

Installation Notes

Installation is performed by machinists or fixture builders using standard fasteners through the four mounting holes, sized for 0.29-inch diameter hardware. Secure the base firmly to a flat, rigid surface to ensure the over-center locking action performs correctly. Verify that workpiece height falls within the bar clearance before final mounting position is set. Do not modify the bar or handle geometry, as alterations affect the over-center lock integrity.
